High-Dose Melphalan, Total-Body Irradiation, and Peripheral Stem Cell Transplantation in Treating Patients With Multiple Myeloma in First Relapse

May 10, 2011 updated by: Mayo Clinic

HIGH-DOSE MELPHALAN CHEMOTHERAPY AND TOTAL BODY RADIATION WITH PERIPHERAL BLOOD STEM-CELL RECONSTITUTION FOR PATIENTS WITH RELAPSING MULTIPLE MYELOMA

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining peripheral stem cell transplantation with chemotherapy and radiation therapy may allow the doctor to give higher doses of radiation and chemotherapy drugs and kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of high-dose melphalan plus total-body irradiation and peripheral stem cell transplantation in treating patients with multiple myeloma in first relapse.

Study Overview

Detailed Description

OBJECTIVES: I. Assess bone marrow reconstitution and peripheral blood cell counts of patients with multiple myeloma treated with high-dose melphalan (L-PAM) and total-body irradiation (TBI) followed by peripheral blood stem cell (PBSC) rescue. II. Assess the efficacy of intravenous L-PAM and TBI for treatment of relapsing/refractory myeloma. III. Assess the tolerability and toxicity of this regimen in patients with relapsing multiple myeloma. IV. Assess response rate and survival of relapsing/refractory patients treated with this regimen.

OUTLINE: Prior to entry, patients will have received 3 monthly courses of standard VAD followed by PBSC collection on Regimen A; those who responded to VAD continue standard VAD to best response and upon relapse (on or off therapy) proceed to Regimen B. Patients with no response to 3 courses of VAD and those with no response to an alkylating-based regimen proceed immediately to Regimen B following PBSC collection. The following acronyms are used: CTX Cyclophosphamide, NSC-26271 G-CSF Granulocyte Colony Stimulating Factor (Amgen), NSC-614629 L-PAM Melphalan, NSC-8806 PBSC Peripheral Blood Stem Cells VAD Vincristine/Doxorubicin/Dexamethasone TBI Total Body Irradiation Regimen A: Stem Cell Mobilization/Harvest. CTX; G-CSF. Regimen B: Single-Agent Myeloablative Chemoradiotherapy with Stem Cell Rescue. L-PAM; TBI (Co60 or linear accelerators of 4 MV or greater); with PBSC.

PROJECTED ACCRUAL: If 9 or fewer or 20 or more responses are seen in the first 50 patients treated, the study will be discontinued.
